This compatibility list applies to all polypropylene nonwovens. The compatibility of the DENSORB binding fleeces has been tested with regard to various chemicals. Due to uncontrollable influencing factors, DENIOS cannot guarantee 100% absorbency. For your safety, we recommend carrying out a compatibility and absorbency test of your chemicals with DENSORB binding fleeces before purchase.

2. For which application are the absorbents needed?

The all-rounder for everyday use: rolls and mats

Whether its for the absorption of liquids during maintenance or cleaning work or in the effective control of leaks - DENSORB mats are true all-rounders. They enable needs-based and economic use in daily operation and are also perfect for permanent use. In the event of a leak, DENSORB mats are suitable for absorbing leaked liquids.

For larger requirements or if your daily need consumption is high then DENSORB rolls are the thing for you. Thanks to the practical perforation, you can take the exact required quantity and use only as much material as is absolutely necessary.

Proven Products for Special Applications

DENSORB socks are indispensable in the fight against leaks. They have a high absorption capacity and are flexible meaning leaks and spills can be contained quickly and easily.

DENSORB cushions are ideal for reliably absorbing leaked liquids or dripping losses in hard-to-reach areas. Cushions are also the best choice for when filling operations are taking place.

To guarantee that leaks are detected, you can install a SpillGuard® - the innovative new hazardous substance warning system available only from DENIOS. Created by our industry experts, this revolutionary alarm system quickly and efficiently detects leaks, releasing a continuous alarm and LED light system over a 24-hour period.

3. How durable do my absorbents need to be?

The higher the durability, the stronger and longer the product can be stressed and remain in use. Depending on the application, you should therefore consider whether you need an extremely strong durability or whether a simple fleece is sufficient for your purposes.

DENSORB rolls and mats are available in 3 different non-woven structures:


DENSORB mats and rolls in Economy SINGLE quality are high-absorbent binding tapes without additional reinforcement on top or bottom. They are suitable for cleaning up leaks or for daily use in cleaning, maintenance and repair work.


DENSORB mats and rolls in Economy DOUBLE quality have an additional lint-free protective layer. This ensures high tear and abrasion resistance. Ideal for almost all applications - for example as a hard-wearing floor covering, for longer-term use or for cleaning work.


Choose DENSORB rolls and mats in Economy TRIPLE quality for the highest demands on durability and cleanliness. The reinforcement on both sides by a liquid-permeable protective layer ensures maximum resistance to tearing and abrasion. Economy TRIPLE absorbents are also lint-free and therefore ideally suited for sensitive applications and surfaces.

The durability and absorption capacity are also dependent on the material thickness of the products. DENSORB rolls and mats are available in two thicknesses, so you can use the suitable absorbents for your application situation.

LIGHT = single material thickness

Very flexible and ideal for absorbing small quantities of liquid during repairs, minor leaks or everyday production.

HEAVY = double material thickness

Extra thick material thickness with high absorption capacity. The high tear strength allows longer term use and / or absorption of higher amounts of liquid, e.g. for larger leaks..
